Foldable desk

ABSTRACT

A foldable desk includes a top and a first leg and a second leg are respectively and pivotally connected to an underside of the top. Two rollers are connected to the underside of the top and one of the first leg and the second leg has two rollers connected thereto. The two legs can be pivoted parallel to the top and the rollers on the top and one of the two legs may roll on the ground.

FIELD OF THE INVENTION

[0001] The present invention relates to a foldable desk wherein the legs can be folded under the top and have rollers so that the folded status of the desk can be used as a slide bench.

BACKGROUND OF THE INVENTION

[0002] A conventional foldable desk generally includes a top and two legs which are respectively and pivotally connected to an underside of the top so that the two legs can be pivoted when the desk is not in use. The foldable legs make the space that the desk occupies is reduced. The foldable desk is usually used as a picnic desk and can be conveniently put in a car trunk. However, the legs cannot be folded to be flat so that it still occupies a certain amount of space. Besides, it is difficult to overlap two or more than two desk within a limited space.

SUMMARY OF THE INVENTION

[0003] In accordance with one aspect of the present invention, there is provided a foldable desk which comprises a top and two rollers are connected to an underside of the top. A first leg and a second leg are respectively and pivotally connected to an underside of the top. One of the first leg and the second leg has two rollers connected thereto.

[0004] The primary object of the present invention is to provide a foldable desk that has rollers when the desk is folded as a flat combination.

[0005] Another object of the present invention is to provide a foldable desk wherein the top has recesses for receiving rollers of another desk that is overlapped thereto.

[0006] The present invention will become more obvious from the following description when taken in connection with the accompanying drawings which show, for purposes of illustration only, a preferred embodiment in accordance with the present invention.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0014] Referring to FIGS. 1 and 2, the foldable desk of the present invention comprises a top 1 and two rollers 30 are connected to an underside of one end of the top 1. A first leg 20 and a second leg 21 are respectively and pivotally connected to an underside of the top 1 at two respective ends thereof. The second leg 21 has a groove 210 defined therethrough and the first leg 20 has a pin 25 which is movably engaged with the groove 210, so that the first leg 20 and the second leg 21 are pivotally connected in a cross type.

[0015] The first leg 20 has two rollers 3 connected thereto and the rollers 3 face the rollers 30 when the desk is expanded as shown in FIG. 2. The top I has four two recesses 10, 11 defined in a top surface thereof.

[0016] As shown in FIG. 3, when the first leg 20 and the second leg 21 are pivoted to a position parallel to the top 1, the pin 25 moves to the other end in the groove 210 and the rollers 3 and the rollers 30 contact the ground, and the folded combination of the foldable desk is in a flat status.

[0017] As shown in FIG. 4, one folded desk can be bridged between two expanded desks by engaging the rollers 30 in the recesses 10 and 11 of the other two expanded desks.

[0018] As shown in FIG. 5 which shows another embodiment of the foldable desk wherein the top 1 has no rollers and the first leg 20 and the second leg 21 each have rollers 3. The two legs 20, 21 are pivotally outward and toward two ends of the top I as shown. The rollers 3 contact the ground so that the folded combination can be moved on the ground by the rollers 3.

[0019]FIG. 6 shows that the two legs 20, 21 have no rollers thereon and two set of rollers 30 are connected to an underside of two ends of the top 1. When the two legs 20, 21 are folded, the two rollers 30 contact the ground as shown in FIG. 7.

[0020] While we have shown and described the embodiment in accordance with the present invention, it should be clear to those skilled in the art that further embodiments may be made without departing from the scope of the present invention.
